David, you can find the pricing for the materials via the 'materials page' - http://www.shapeways.com/materials/ (linked to under the support dropdown at the top of every page) but it doesn't look like the page has been updated with colour changes yet.

As for, 'cannot be delivered in the proper timeframe', that's happend to me before, I chose continue and everything was delivered on time. I think it's just a glitch in the system.

I'm not too particular about the exact color of my items..I just don't want them ALL white because, like somewhere else I read, it's hard to see and differentiate the different pieces when they are all white. It's easier to see the contours and things.

Also, what's the detail difference between SWF and white detail? Yes, I've seen their respecitive charts but is there really a detail difference? I need as much detail as possible, of course, but I also like a smoother surface...a surface that won't keep flaking off in powder like the SWF does. I have SWF parts that rub against each other and they keep grinding away powder. Is the white detail like a clear acrylic? Will the white detail flake off like powder too or no? I need a little flexiblity but more so I need it to not keep flaking off when rubbed together.

WSF and detail materials are completely different... mostly because of the way that they're printed. WSF is basically plastic powder heat bonded and detail is a polymer that's cured under UV light. In terms of detail level, the detail materials win over wsf, but detail doesn't have much flexibility or strength at small sizes. Detail materials are solid and don't flake, though they can show some 'stepping' e.g. Kraken in Crystal - the arms are about 0.4mm diameter.

For sealing & smoothing wsf, have a look in the Post Production sub-forum, super glue seems to be a popular option and there was a thread recommending a furniture polish/varnish too. Personally, I'm experimenting with dipping wsf in watered down acrylic paint and I've also used Pebeo Vitrail paints on wsf to good effect.
